Oh no! We have new IP addresses.

Part Trois

By The Network Team

why did you do this to me
Why did you do this to me?
  • New IP addresses should provide enough addresses for whole herds of devices
  • New IP addresses will allow for organization within the school and will free BLTC of having to provide addresses for most traveling folks
  • We finished the whole public IP address transition last spring and it is time to move forward.
so now what does this all mean
So now what does this all mean?

In the past, we asked that you add the new addresses whenever you move around the school as you help users and their machines.

Eventually, the older IP addresses will become unusable.

Also, some sites have had trouble when there was a mixture of old and new IP addresses.

kcs ip address 101
KCS IP Address 101

Prior to this issue of IP addresses, your school had two types of IP addresses.

Public Addresses

The public addresses were the numbers that were 66.4.X.X numbers and are visible to the outside world. Most schools have very few of these numbers. These numbers have been changed to 96.4.X.X.

Private Addresses

The Private addresses were the numbers that are 10.x.x.x . Most of the computers in your school have these addresses.

Each school has at least four sets of 254 of these numbers.

the ip address anatomy
The IP Address Anatomy

An IP address consists of four sets of

numbers (octets) separated by a period.

An example of an IP address would be

10.55.7.174

Computers use IP addresses to help find where to send and receive data. Each computer must have a unique IP address.

the new ip address
The New IP Address

-The new IP issue allows a huge number of IP addresses for each school. The first digits will always be 10.

-The second octet will be the school’s number that the BLTC was given

-The third octets vary from 7-111 based on what type class that the computer is in

-The fourth octet will be a number between

1 and 254.

description of current problems involving ip addresses
Description of current problems involving IP addresses

Some folks who have changed computers from the old 10.145.x.x addresses to the new 10.xxx.xxx.xxx addresses have found that they may have trouble printing to network printers that they used to be able to print to.

the cause of the problem
The cause of the problem?

The problem of not being able to connect to printers and such would be an issue in the router.

The router provides all of the IP address information in the school in the form of files called Routing Tables.

When new Routing Tables were put into the router, the two routing tables (10.145.x.x and 10.x.x.x) were not linked together.

the cause of the problem13
The cause of the problem?

Routing and routing tables are handled by the fine engineers at ENA (Education Networks of America) in Nashville.

Some of our schools have the routing tables linked together and some do not. There is no way for the Network Team to do much about this but complain.

So,

Be aware that when you change IP addresses on computers, you might also change the IP addresses on the printers too.
